FaRTs appetite hasn't caught back up fully yet. But, this morning he did nibble on a bit of raw shrimp, take a big earthworm down like spaghetti, and nibble the end off of a slice of golden delicious apple.
He's currently in 84F (28.88C). I don't know how hot the tank actually rose to but, after replacing a third of the water the temp dropped to 92F (33.33C). The water was hot enough to turn the skin on my hands and forearms red. It was easily around 108-110F (42-43C).
